In many rapidly advancing areas of technology, such as fabrication of new
nanostructured materials, development of biocompatible biomaterials and control of
targeted drug delivery and medical diagnostic systems, progress depends on our ability
to control interactions at the nanoscale level. My work over the past years has aimed
at contributing to a fundamental understanding of the interactions between surfaces
that range from heterogeneous micropatterns to artificial biomembranes using atomic
force microscopy techniques.

During this presentation two representative examples will be discussed: surface pattern
recognition by a colloidal particle and adhesion of integrin receptors to biomimetic
substrates. The first one demonstrates that by varying the size and density of a surface
pattern one can potentially prepare surfaces able to direct particle attachment and
adhesion at desirable positions. The second one shows the use of a model biomimetic
system to investigate unbinding processes between ligand-receptor pairs. The
implications of these findings in making ordered nanostructures by colloidal assembly
and designing biomaterials with specific functionality will be discussed.
